Instructions

  1. Step 1: Preheat oven to 400°F. In a small bowl, combine 3 tbsp olive oil, 4 minced garlic cloves, 2 tbsp chopped fresh rosemary, 1 tbsp lemon zest, 2 tbsp lemon juice, 1 1/2 tsp salt, and 1 tsp black pepper to make a marinade.
  2. Step 2: Rub the marinade all over a 2 lb pork loin roast and place it in a roasting pan. Arrange 1 lb halved baby Yukon gold potatoes around the pork, tossing the potatoes with any leftover marinade.
  3. Step 3: Roast in the preheated oven for 45-55 minutes until the pork reaches an internal temperature of 145°F and potatoes are golden and tender, stirring potatoes halfway through cooking.
  4. Step 4: Remove pork and potatoes from oven. Let pork rest for 10 minutes before slicing. Serve pork slices with the roasted potatoes.
